Bugfix ISO9613-1: Functions for absorption factors now return proper factor which can directly be applied to audio signals (!2) · Merge requests · Institute of Technical Acoustics (ITA) / ITABase · GitLab

Hinweis: Beginnend mit dem nächsten Release (GitLab 17.7) wird OpenSSL 3 verwendet. Alle TLS-Verbindungen erfordern TLS 1.2 oder höher. Schwächere Chiffren werden nicht mehr unterstützt. Die Verschlüsselung muss mindestens eine Sicherheit von 112 Bit aufweisen. // Starting with the next release (GitLab 17.7), OpenSSL 3 will be used. All TLS connections require TLS 1.2 or higher. Weaker ciphers are no longer supported. Encryption must have at least of 112 bits of security. https://docs.gitlab.com/ee/update/versions/gitlab_17_changes.html#1770

Philipp Schäfer requested to merge bugfix/ISO9613_air_absorption_factor into develop Sep 05, 2023

now convert from dB to linear assuming sound pressure instead of energy ( 10^(L/20) )
factors now refer to remaining "energy" instead of absorbed "energy"
